Intelligent Trust Management provides a centralized security facility that gives system components a flexible mechanism for implementing security policies. System components such as applications create a request describing an action that needs to be checked against an appropriate security policy. The request is given to a trust system that determines which policy object applies to the request, and may pass request arguments to the policy. The policy objects include executable code that uses any arguments along with dynamically obtained variable information to make a decision. The decision is returned to the system component, which then operates accordingly. Policy objects may maintain state and interface with the user independent of the system component in order to obtain information to make their decisions. Policy objects may call other policy objects and/or mathematically combine the results of other policy objects to make a decision.

A trust system and method is disclosed for use in computing devices, particularly portable devices, in which a central Authority shares secrets and sensitive data with users of the respective devices. The central Authority maintains control over how and when shared secrets and data are used. In one embodiment, the secrets and data are protected by hardware-rooted encryption and cryptographic hashing, and can be stored securely in untrusted storage. The problem of transient trust and revocation of data is reduced to that of secure key management and keeping a runtime check of the integrity of the secure storage areas containing these keys (and other secrets). These hardware-protected keys and other secrets can further protect the confidentiality and/or integrity of any amount of other information of arbitrary size (e.g., files, programs, data) by the use of strong encryption and/or keyed-hashing, respectively. In addition to secrets the Authority owns, the system provides access to third party secrets from the computing devices. In one embodiment, the hardware-rooted encryption and hashing each use a single hardware register fabricated as part of the computing device's processor or System-on-Chip (SoC) and protected from external probing. The secret data is protected while in the device even during operating system malfunctions and becomes non-accessible from storage according to various rules, one of the rules being the passage of a certain time period. The use of the keys (or other secrets) can be bound to security policies that cannot be separated from the keys (or other secrets). The Authority is also able to establish remote trust and secure communications to the devices after deployment in the field using a special tamper-resistant hardware register in the device, to enable, disable or update the keys or secrets stored securely by the device.

A trust rating factor (TRF) based upon data collected for players participating in previous online games sessions is used in determining official results for an online game session when different results are reported by the participants. Counters corresponding to each of a plurality of parameters related to conditions that arise during or at the end of a game session are employed in determining the TRF for each player. For example, if one of the players may have experienced a packet bombing that interrupted normal data communication, a counter related to that condition will be incremented for all players in the game session. If all of the players report results that are consistent at the end of the game session, the TRF of each player is improved. A separate TRF is determined for each game title in which a player participates.
